Alberta Health Services had conducted 60,508 tests as of Friday afternoon. New data shows local transmission, now at 137 cases, has been "relatively constant over the last 10 days."

In late March, the province shifted its testing approach to focus less on returning travellersand more on the at-risk population and health care workers.

"Every one of these cases is concerning, and we follow up with every case to ensure that we're limiting spread. However, it does not seem at this moment that we're seeing a rapid rise in local transmission."

Alberta's top doctor also announced AHS is limiting visitors to hospitals starting Friday, and encouraged virtual visits instead.

"With few exceptions, patients in hospital will no longer be able to have any visitors in person."

While there are outbreaks of COVID-19 at several continuing care homes across Alberta, Hinshaw said there are no confirmed cases at jails or homeless shelters.

Kenney, who said this was the toughest week of the pandemic, said the province would reveal new coronavirus data and potential scenarios next week.

"I can assure Albertans today, however, that the modeling indicates that we have the health care equipment, personnel and supplies needed to cope with anticipated hospitalizations, including in intensive care units and including the use of ventilators."

As of 4:55 p.m., there were 12,548 cases of COVID-19 and 187 deaths in Canada.

HOW THE COVID-19 PANDEMIC UNFOLDED THROUGHOUT THE WEEK

On Monday, Alberta shifted its testing focus and increased it to full capacity after a supply shortage.

The result was a spike in cases on Tuesday, Wednesday and Thursday. The chief medical officer of health expressed concerns as cases neared 1,000, but explained her biggest worry is the steady two per cent positive results out of the tests conducted daily.

Hinshaw's updates this week have also centred on the several outbreaks at continuing care homes across Alberta.

"At this moment, my greatest concern is about the health and safety of those in continuing care and other congregate settings," Hinshaw said Wednesday.

A day later, she implemented new measures to protect seniors and staff at continuing care homes.

Staff are now required to immediately tell health officials when a coronavirus case is suspected, and workers employed at more than one facility must notify their supervisor if they have worked at another home with a suspected of confirmed case.
